µPD64084

3-Dimensional Y/C separation LSI with On-chip Memory


Overview Features Ordering Information Block Diagram


Overview

The µPD64084 realizes a high precision Y/C separation by the three-dimension signal processing for NTSC signal.
This product has the On-chip 4-Mbit memory for flame delay, a high precision internal 10-bit A/D converter, D/A converter, and adapting 10bit signal processing (only for luminance signal) and high picture quality.
The µPD64084 is completely signal chip system of 3-D Y/C separation.
This LSI includes the Wide Clear Vision ID signal (Japanese local format) decoder and ID-1 signal decoder.
